A Litrpg, post-apocalyptic earth, based in Australia. The system will be introduced due to an expansion of dark energy and the limited size of the universe, which in turn have implications for the universe's fate. There will be a 'Big Rip', which will cause the universe to break into a multiverse. At least they solved the equation to everything, and everything goes to shit.

Survival is the primary goal, introducing the multiverse, understanding and manipulating dark energy, dark matter and anti-matter. These will be the building blocks for the classes that allow amazing things beyond our comprehension. The mechanics will be unknown to the average person as it comes from higher physics but will present itself as a gaming screen.

The universe is a living sentient creature and is about to split into new baby-verses, as happened to it billions of years ago. These will then interact with other baby-verses and join the big 'them' group within 100,000 years. The Parent-verse of our Universe is akin to a deity; this creature created the system so that new lifeforms could adapt to the greater multiverse. Until a max saturation of dark energy, the system doesn't exist for baby-verses.

Dark energy affects everything, from the minor virus to planets. Earth will be separated into 16 new Earths; the extra materials will come from dark matter and dark energy to abide by the Law of Conservation of Matter. So, every person will be placed randomly on one of these new Earths. A genetic family of said MC within 5 km will be transported to the same earth. This will allow communities to still function.
